Translate characters: run replacements based on single characters and character sets. More information:

  • Replace all occurrences of a character in a file, and print the result:

tr {{find_character}} {{replace_character}} < {{path/to/file}}

  • Replace all occurrences of a character from another command's output:

echo {{text}} | tr {{find_character}} {{replace_character}}

  • Map each character of the first set to the corresponding character of the second set:

tr '{{abcd}}' '{{jkmn}}' < {{path/to/file}}

  • Delete all occurrences of the specified set of characters from the input:

tr -d '{{input_characters}}' < {{path/to/file}}

  • Compress a series of identical characters to a single character:

tr -s '{{input_characters}}' < {{path/to/file}}

  • Translate the contents of a file to upper-case:

tr "[:lower:]" "[:upper:]" < {{path/to/file}}

  • Strip out non-printable characters from a file:

tr -cd "[:print:]" < {{path/to/file}}
